百叶窗

There is always something to be done: a tin-tack here, a Venetian blind to put straight, a fan to nail up , or part of a carpet to nail down --all of which I can do with my pipe in my mouth; while Carrie is not above putting a button on a shirt, mending a pillow-case, or practising the "Sylvia Gavotte" on our new cottage piano (on the three years' system), manufactured by W.

总是有一些事情可做：钉个钉儿，拉直百叶窗，在墙上钉把扇子或是钉牢地毯的某个地方，所有这些我抽着烟就轻松地做了。卡丽却只能给衬衣钉个纽扣，缝补一下枕套或是在我们新买的竖式小钢琴上练练《西尔维亚加伏特舞曲》。

She could hear the clatter of iron shutters being cranked up over at the amusement arcades.

2According to requirement of suppressing stray light in two-mirror system, vertex coordinate formulas of inner baffle are deduced based on geometrograph in the case of certain obscuration, viewing field and vignetting. In order to reduce the obscuration, conical baffle of secondary mirror is ameliorated into a shutter one. Outer baffle is designed when angle of stray light suppressing is foregone and the vanes are designed in C-language program. Finally, the same-height vanes in drawtube between primary and secondary mirrors are designed for further suppressing the stray light in two-mirror system.

给出双反射系统杂散光消除设计的具体要求，结合作图法，推导出考虑视场大小及初始中心遮光比确定时，主次镜内遮光罩顶点坐标公式；讨论考虑渐晕时主次镜内遮光罩的设计；为了减小初始中心遮光比，将次镜锥状遮光罩改进为百叶窗式结构；设计在杂散光源抑制角已知时的外遮光罩，并利用C语言实现程序化设计其挡光环的方法；设计主、次镜间镜筒内壁上等高挡光环，进一步抑制双反射系统的杂散光。

The general correlations for j and f factors were derived by regression analysis and F test of significance.

同时通过对20种不同结构参数百叶窗翅片的336个试验数据点进行多元回归和F显著性检验，获得了j因子和f因子的经验关联式。

A R-C system with foci of 2 m and f-number F/4 was taken for an example, the principles of stray light eliminating and evalutiong in reflective optical system was put forward. Lens hood in the main mirror, lens hood outside and window shade, lens hood in the secondly mirror were designed by CAD modeling.

以焦距为2 m，相对孔径为1/4的R-C系统为例，介绍了利用计算机仿真技术进行消杂散光设计和评价的原理，结合CAD建模进行了主镜内遮光罩、外遮光筒、次镜百叶窗式遮光罩的设计。
